Just in case he can't figure out how to go back a page to find this again:
Before you do anything I'm about to tell you, force update your game with the option button in the minecraft launcher.
After that, follow these simple steps to patch your game.
1. Download the link in my last post.
2. Download and install winrar or 7zip (preferably winrar), if you don't already have one of them.
3. Right click your minecraft.jar, which is in the bin folder of your .minecraft folder.
4. Click 'Open with Winrar'
5. Leave that window open for now.
6. NOW go to your file that I told you to download in my last post.
7. Right click and open with winrar.
8. Copy all the files from inside the optifine folder (the one you downloaded) into your minecraft.jar
That's it. Move your texture pack into your texture pack folder after all that and it should work.
